This patented radiant 4000-18000 BTU Liquid Propane heater connects directly to two 1 lb. cylinders and is the perfect solution for heating enclosed spaces like cabins up to 400 sq. ft. An integrated fan increases the heating capacity of this unit, blending radiant and convection style heat to give you the best of both worlds.

Two swivel regulators give you the ability to adapt usage from disposable cylinders to a remote gas supply with the purchase of a single hose and filter

To light the unit, simply push and rotate the knob - built-in Piezo sparking mechanism will take care of the rest

With the Oxygen Depletion Sensor (ODS) and accidental tip-over safety shut-off, you can be sure that you will enjoy years of comfortable indoor safe heat

Extremely Satisfied!I bought my Mr. Heater Big Buddy propane heater mainly for a back-up heater in case we lose electricity. As luck would have it, two weeks later our electricity didn't go out but our heat pump did. I used the big buddy heater for two days in temps that got as low as 7 degrees. It heated my living room, kitchen and hallway to a very comfortable temp. Highly recommend.

Easy to work with.Bought this for extra heat for Christmas, and it worked great. No assembly required. East to install canisters. Might have to work with it to get it to light first time. Takes it a little bit to get the gas flowing through the line. Does the job for me.

I bought this heater and the filter and hose and we love it and the box says it's indoor safe it's perfect I just hope it's actually indoor safe as I have a one year old and like as far as it not letting harmful fumes into our home it is safe right.?

Asked by: Code

Thank you for your inquiry. This heater is certified for indoor use. There is an oxygen depletion system that is installed on the unit that shuts the heater off if the oxygen drops below 18%.

I have a smaller version of this heater I use in my hunting blind. it keeps me warm but on colder days I can get cold on the opposite side of the heater. Would this heater be too big to use in a hunting blind? My blind is 4' by 4' / 6' height.
